This invention relates to guards for tools and consists in the provisionof a guard or sheath adapted to receive and protect edged tools such as,for example, chisels, bits, and analogous tools.

An object of the invention is to provide a guard or sheath of thecharacter above mentioned that is characterized by simplicity andeconomy of structure. 1

The invention, together with its objects and advantages, will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure l is a side elevational view illustrating an application of theguard or sheath.

Figure 2 is a top plan view thereof.

Figure 3 is an end elevational view thereof.

Figure 4 is a perspective view of the forward end of the sheath.

Figure 5 is a perspective view of an end strap forming part of theinvention.

Figure 6 is a sectional view through a slightly modified form of theinvention.

Figure 'l is a bottom plan view of the form of the inventionshown inFigure 6.

Figure 8 is an end elevational view of the second form of sheath.

Referring to the drawings by reference numerals, and reference being hadparticularly to the form of the invention shown in Figures 1 to 5inclusive, it will be seen that the guard or sheath indicated generallyby the reference numeral I0 is formed from a single oblong blank ofmetal or other suitable material cut, shaped, and dimensioned to providetwo complemental sections Ii and i2 integrally joined at one end toprovide a closed end It for the sheath. At the end I3 the section i2 isslightly curved away from the section I I to provide inwardly from theend l3 a stop it, and due to the inherent resiliency of the materialused the section I! is normally urged in a resilient manner away fromthe section II of the scabbard or sheath.

The section I: has downturned longitudinal edge portions or flanges i5directed towards the section I l and adapted to engage the sides of theblade of the tool inserted in the scabbard for retaining the toolproperly within the scabbard or sheath.

At the open end thereof, that is, at the end thereof opposite to theclosed end l3, the sections II and I2 oi the scaobard are connectedthrough the medium of a strap l6 that has an intermediate portionthereof secured in any suitable manner transversely to the section II.opposite end portions extending between or bridging the space be- Inactual practice, the blade iii of the tool is 10 inserted in the sheathin an obvious manner and at the beveled edge end thereof the tool willengage the stop I4 in such a manner as to prevent the sharp edge of thetool from coming into forceful contact with the metal or material fromwhich 15 the sheath or scabbard is formed. In this connection, it willbe noted that the working or sharp edge of the blade of the tool whenthe tool is fully inserted in the scabbard will come into contact withthe strip l1 which latter, as before stated, is of an absorbent materialand may be provided with oil or any other suitable anti-rust solutionfor protecting the edge of the blade of the tool against rust andcorrosion.

The form of the invention shown in Figures 6 to 8 inclusive issubstantially identical with that shown in Figures 1 to 5 inclusive withthe exception that in the second'form of the invention, the strap i6 isdispensed with and the flanges i541 of the section i2 at the open'end ofthe scabbard or sheath are provided with integral spring fingers 20 thatat their free ends are formed with heads 2! adapted to engage thesection II of the sheath in a manner clearly shown in Figure 8 to holdthe sheath in what may be termed a closed condition. In this connection,it will be noted that the section I20, of the scabbard or sheath istransversely curved as clearly shown in Figure 8 and to facilitate thewithdrawal of the blade l8 of the tool from the scabbard the operatorwith the thumb may exert a pressure on the section l2a adjacent the openend of the Scabbard in a manner to flex the section i2a inwardly towardthe section Na and thereby cause the heads 2| of the spring fingers 20to spread outwardly out of engagement with the sec tion Ha. thuspermitting, upon release of said pressure, the section I2a, due to itsinherent resiliency, to spring outwardly away from thesection Ila or, asmay be stated, opening the scabbard in a manner to permit the blade ofthe tool to be to provide two complemental sections, one of saidsections at the free end thereoi having integral resilient tongues atopposite sides thereof and provided with heads for engaging the other ofthe sections to releasably retain the sections against the tendencythereof to spread apart due to the inherent resiliency of said sections.

2. A scabbard for tool blades formed from an oblong strip of metal bentintermediate its ends to provide two complemental sections. one of saidsections at the free end thereof having integral resilient tongues atopposite sides thereof and provided with heads for engaging the other ofthe sections to releasably retain the sections against the tendencythereof to spread apart due to the inherent resiliency of said sections,said one section being curved transversely as and for the purposespecified.

3. A scabbard for tool blades formed from asingleelongatedbiankofsheetmetalandhavins a pair of elongated sidesections integral at one end and mutually separated at the longitudinalside edges thereof. one of said sections having integral side flangesextending longitudinally thereof for guiding the blade passed into thescabbard between said side sections, and means at the free ends of theside sections and engaging therewith to limit the normal tendency of thesections to spring outwardly from one another due to the inherentresiliency of the material used.

4. A tool blade scabbard of sheet metal having elongated side sectionsintegral at one end and mutually separated at the longitudinal sideedges thereof, one of said sections having integral side flangesextending for substantially the 15 full length thereof and projectingtherefrom toward the other of said sections, and a strap of substantialloop form embracing the side sections adjacent the free ends thereof.
